The invention provides a crane with high weighing accuracy. The crane comprises an upper trolley, a lower trolley, a weighing device and a horizontal pull rod device, wherein the upper trolley comprises an upper trolley frame and a hoisting device; the lower trolley comprises a lower trolley frame and a running device; the weighing device is arranged between the upper trolley and the lower trolley; and the upper trolley is connected with the lower trolley through the horizontal pull rod device. According to the crane, the hoisting device is distributed on the upper trolley, the upper trolley and hoisted goods act on the weighing device between the upper trolley and the lower trolley, all of the gravities of self weight of the upper trolley and the hoisted goods are weighed, the weighing precision is not affected by pulley multiplying power and the wrapping manner of a steel wire rope, the impact on the weighing precision caused by horizontal force is reduced by the horizontal pull rod device simultaneously, the weighing error is reduced, and the weighing precision is greatly improved.
